Improvement in loom selvage-guards



UNITED STATES PATENT OFFICE JOSEPH CLAYTON, OF DRAOUT, MASSACHUSETTS.

IMPROVEMENT IN LOOM SELVAGE-GUARDS.

Specification forming part of Letters Patent No. 148,036, dated March 3,1874; application tiled May 31, 1873.

To all whom 'it may concern:

Be it known that I, J osEPH CLAYTON, of Dracut, in the county ofMiddlesex and State of Massachusetts, have invented a new and ImprovedSelvage Guard or Regulator, to be used on looms in weaving textilefabric, of which the following is a full, clear, and exact description,reference bein g had to the accompanying drawings making part of thisspeciiication, in which- Figure l represents an inner side, Fig. 2 aplan or top view, and Fig. 3 an end elevation, being the forward end, ofa common loom-temple with my improvements thereunto applied forpractice.

This invention relates to certain new and useful improvements in selvageguards or regulators, to be used ou looms lin weaving textile fabric,and combined with and operated by the temple, as hereinafter described.This invention has for its object, first, the formation of a better,more perfect and even selvage on woven fabric, a selvage that shall beof the same thickness, tension, and elasticity, and, if desired, thesame texture of the fabric, and which shall not cockie or turn over asthe fabric is wound upon the cloth roll or beam; second, my inventionhas for its object to protect the ends or outer dents of the reed byholding the selvage-threads out when the lay and reed advance to beat upthe filling, and also when the reed and lay recede third, my inventionhas for its object to protect the selvage-guard from injury fromstopping shuttles, as hereinafter described.

When myimproved selvage-regulator is com bined with the loom-temple, asshown, and operated by or simultaneously with the temple, I generallyform the arm G, about as shown in the drawings, with a center hub orbearing, j', which is fitted to and works on a stud, c4, on'the end of aslotted plate, d2, adjustably secured to a second slotted plate, d3,adjustably fastened to the yielding bar B of the temple. l then applythevroll I) to the stationary side of the temple, as shown, and form therear end of the arm G with a tail or guide, g1, and a cam or incline, m,to Work beneath the roll b, and depress the rear end of the arm, andraise its forward end and the points g from their place between theselvagethreads, which is ing to any part of the burr or jaw of thetemple.

When the lay recedes, after beating up each filling-thread, the templemoves forward, as

usual, and the connected arm follows it. At

such times the forward end-of the arm and points g are depressed, tobring the latter between the selvage-threads, by means of acoiledspring, n, one end of which is fastened to the arm, and the other end tothe stud-plate d?, the spring n encircling the stud c4.

The roll b is of suicient length to allow of any desired adjustment ofthe arm G transversely with the temple. The plate d carries a fender,g2, which projects downward, forward of the feed end of the temple, andoutward a little beyond the points g, or the heads in which they areset. The object of lthis fender is to prevent injury to the points byshuttles, which sometimes stop in the web, opposite the temples, just asthe lay advances to beat up the filling. The shuttle being struck by thereed would bend or break the points, and the fender saves them.

The object of the longitudinal adjustment of the arm is to carry thepoints farther from or nearer to the feed end of the temple, and therebyto catch and hold the lling at any desired distance from the fabric lastformed, so as to cause a greater or less degree of slackness of thefilling against or around the outer selvage threads, the points 1orprongs g passing between such selvage-threads in time to receive thestrain of the filling caused by the velocity of the shuttle at each beatofthe lay.

For the want of a selvage-regulator in ordinary weaving, I have foundthat the fabric is more or less affected by the tension of the fillingfor several inches inside of the selvage.

When the cloth is a little more forward tox'vard and at the selva-gethan in the middlethe temples, varying from two to eight inches,

according to the kind of fabric.

rlhe extra strain on the edges of the warp tends to make them longer,While the eXtra strain of the filling tends to make the fabric narrowerthan its natural Width, and this narrowing or drawing in of theselvage-threads causes them to cut and Wear the outer dents oi' the reedmore rapidly than the middle dents are Worn.

The difficulties above enumerated are beyond the capacity of the templeto overcome, as it has nothing to prevent the illing being driven homeat the instant its tension is greatest. By the use of my improvedselvage guard or regulator all the labove-named difficulties areovercome; and, besides this, the outer dents of the reed, or those dentsnearest the ends, will be protected by keeping the selvage-threads out,or. in line With the forming fabric, Which will shrink a little afterpassing the temples, and sufficiently to carry the edges clear of theupright parts of the sewage-regulator.

A Xed bar or incline may be substituted for the cam-operating roll b,and made to Work successfully by lubricating the cam.

'I claim as my inventionl. The arm Gr, constructed as described, withcamion, guide g1, and prongs g, in .combination With the adjustablestud-plate d2, spring u, and slotted plate d3, and with the roll blandthe temple, all arranged and operating in the manner and for the purposespecified.

2. The fender g2, in combination with the adjustable plate d3 andthe'temple, and operating to protect the points g, asdescribed.
